Looking for seasonal themed names other than [name_f]Autumn[/name_f], [name_f]Summer[/name_f], [name_u]Winter[/name_u] and [name_f]Spring[/name_f].
[name_m]Leif[/name_m]
[name_f]Tessie[/name_f] (means summer)
[name_f]Fiona[/name_f] (has the summer feel to me)
[name_u]Red[/name_u] (fall)
[name_u]Ocean[/name_u] (summer)
[name_f]Hattie[/name_f] (close to hotty - summer)
[name_u]Aviv[/name_u] (spring in Hebrew)
[name_f]Suvi[/name_f] (summer in Finnish)
[name_f]Theresa[/name_f] (may be derived from the Greek word for summer)
[name_f]Vera[/name_f] (derived from the Albanian word meaning summer)
[name_f]Primavera[/name_f] (spring in Spanish)
[name_f]Flower[/name_f] names make me think of spring, but you could find flowers from each season. Things like [name_u]Valentine[/name_u]/[name_u]Noel[/name_u]/[name_f]Noelle[/name_f] could work for winter.
